Original Release date: 25 Feb 2005 | Last revised: 25 Feb 2005

Overview

AWStats performs inadequate validation on user-controlled data that is supplied to the pluginmode parameter. Exploitation of this vulnerability may allow a remote attacker to execute arbitrary commands.

Description

Inadequate validation on input supplied to the pluginmode parameter may allow an attacker to execute PERL commands (i.e. the system() function), which can be used to execute arbitrary operating system or shell commands with the privileges of the web server process.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary commands or cause a denial-of-service condition.
